A Real Time Simulation and Forecasting Application of Yellow River Diversion Project Conveyance Line

The paper is concerned with a real time simulation management and forecasting system for water diversion infrastructure project. The Wanjiazhai Yellow River Diversion Project is a large-scale inter-basin water diversion undertaking with the target capability of transferring 1,200 million m3 of water annually. The project is one of many strategic measures to alleviate water shortage problems in the area, particularly for the three cities of Taiyuan, Datong and Shuozhou. DHI´s MOUSE model has been applied as an application running in real time to provide short-term security checking and also to develop long-term optimal operational strategies to the entire conveyance system. A key aspect of the development of the system was the understanding of the differing control strategies between the process modelling and the SCADA system, as the model was required to be able to accurately predict the true operation of the system during emergency conditions and with operator intervention. The paper describes the applications development including the unique aspects of producing operational forecasting over a 7 day period to develop safe, economic and reliable operations in an hydraulically complex water diversion scheme.
